Comparative Study Between Smart Bur II and Traditional Carbide Bur in Selective Removal of Caries in Permanent Molars

caries was removed using a slow-speed handpiece and round carbide burs in sizes #12, #14, and #16, based on the lesion's size. When hard dentin was found using a dental probe, carious dentin removal was stopped.

carious tissue was removed utilizing smart polymer burs of sizes #4, #6, and #8, depending on the cavity's size, running at a slow speed without water coolant, in circular motions from the center of the lesion outward. Carious dentin removal ceased when the instrument became macroscopically abraded and sharpened and could no longer remove tooth tissues.
